It might be interesting to talk about all the different Url parsing APIs in Microsoft as it's pretty confusing to decide whether to use shwapi Url* functions, or something like urlmon CoInternetParseUrl, or something like wininet InternetCrackUrl {there's are others as well}.http://blogs.msdn.com/freeassociations/archive/2005/05/19/the-bizarre-and-unhappy-story-of-file-urls.aspx#696173Sat, 12 Aug 2006 05:48:14 GMT91d46819-8472-40ad-a661-2c78acb4018c:696173Better Living through Software » Blog Archive » A change in URI parsing between IE7 and IE6PingBack from <a rel="nofollow" target="_new" href="http://www.netcrucible.com/blog/2005/11/07/a-change-in-uri-parsing-between-ie7-and-ie6/">http://www.netcrucible.com/blog/2005/11/07/a-change-in-uri-parsing-between-ie7-and-ie6/</a>http://blogs.msdn.com/freeassociations/archive/2005/05/19/the-bizarre-and-unhappy-story-of-file-urls.aspx#752479Wed, 13 Sep 2006 21:32:35 GMT91d46819-8472-40ad-a661-2c78acb4018c:752479IEBlog <br>While working on IE7 application compatibility, we’ve seen many cases of interesting and strange invalid...http://blogs.msdn.com/freeassociations/archive/2005/05/19/the-bizarre-and-unhappy-story-of-file-urls.aspx#1224589Wed, 06 Dec 2006 20:45:22 GMT91d46819-8472-40ad-a661-2c78acb4018c:1224589IEBlog<p>Invalid file URIs are among the most common illegal URIs that we were forced to accommodate in IE7.

If I pass in your example of a &quot;healthy&quot; URL above: &quot;file:///c:/foo/bar&quot; it gives back as canonical the legacy version &quot;file://c:\foo\bar&quot;. I assume this is for backwards compatability, but it's annoying because I want to do the right thing with file URLs.</p>
